cdecl is a small utility that translates complex C declarations into plain English and can also help construct declarations from a description.
Why it is useful
Pointer-heavy declarations can be difficult to read at a glance. A declaration such as a pointer to a function returning another pointer becomes easier to reason about when a tool spells out the structure.
Typical usage
cdecl explain 'int (*f)(char *)'Package names and command syntax can vary slightly by distribution or implementation, so use the local manual page after installation.
This replaces an older malformed duplicate-title note and keeps the page as a concise C programming reference.
